Application Iledy `(h'tober 12, 1925, SeralNo. 61,913,`an. in Australia August 3, 1925.'

My invention relates to improvements in machines for fleshing furred skins, the ob ject of the same being to provide means whereby a greater area of the skin can be ex-r posed to the cutting knives thank is at present the case with' machines at present in use, and also to provide means whereby the depth or thickness of the cut can be evenly ad justed; t

Incarrying my invention into effect I provide a cylindrical casing havingbearings at eachend, buttbeing opened longitudinally at one side.'v 'Ihis casing is furnished with a kcentral rotatably mounted spindle upon each end vof which there is va spider for carrying a series of helicallyj curved knives arranged somewhat onthewell known principle of the knivesv 'of a lawn mower. The spindle is may rotate' with but little friction and'can be furnished with a pinion wheely or sprocket wheelor other 'driving device at one end so that it may receive rotary motion from a driving element.

Upon each side of the open portion of the cylinder I mount` adjustable guides which are capable of ysliding in grooves and are adapted to increase or decrease the relatively exposed area ofthe knives so that the cut can be made from a comparatively slight shaving to any predetermined depth. Provision is made fork lubricating the bearings.

But in order that my invention may be more clearly understood I will now describey thesame by aid of the accompanying illustrative drawings wherein :--V

Fig. l is a vertical front elevation of the machine. t

Fig. 2 is a sectional X-Y of Fig. 1.

Fig. 3 vertical elevation of helical knife. FFig. 4 end view of knives projected from In each of the illustrations similar letters ofy reference are used to denote similar or corresponding parts wherever they occur.

In the drawings a is a bench or platform through which a circularhole is cut as indiplan throughl the line cated by dotted lines and beneath which a shute b is arranged to receive and deflect waste material from the machine.

I construct from sheet metal or malleable cast metal a frame or case 'c preferably of cylindrical formation, a. portion of which is open as illustrated-'in the drawings and along one edge of the open portion I provide a tangential thickening plate C; at the base' of the cylinder I form legs or lugs preferably three in number as indicated yat. (i througl'i which there is a hole for the foundation bolts e whereby it is secured to the bench.

Near to the base of the cylinder I also ar range a lower fixed spider 7*' which may form anintegral portion of the ycasing or may be attached thereto by countersunk studs or screwscr other convenient means and within this spider I form a cup f to act asa bearing and I provide a ball race'therein. i'

At'the top of the structure I arrange a Acorresponding bearing g whichr may also be provided with a ball raceand can be securedbyr a screw threaded. stubVK fg whichV passes i with bolts or studs 7c wherebythe helical Vknives Z are secured to thespiders as illusf -tratedl rIhese knives are preferably three in number `and are arranged in the manner illustrated and may have their cutting edges slightly curved in the direction of their traverse as more clearly indicated at Z in Fig. 3 of the drawings as is the custom with fleshing knives, the direction of rotation being indicated by the arrows in Figs. 2 and 3.

The upper spider may have a short spindle seated therein adapted to be supported within the upper bearing. The lower kspider is keyed or otherwise secured to a spindle m which may be adjustably held in position by the nuts n and extends downwardly below the bench or platform and is fitted with a bevelled gear wheel 0 which registers with a bevelled gear wheel p mounted upon the horizontal driving shaft g which is supported by the bracket 7' and receives rotary motion from any convenient source of power. This `driving gear, however, may be varied according to preferments and circumstances.

Upon one side of the opening in the frame or case I mounta vertical flat sliding plate s having horizontal slots or slideways s near each end thereof, and I also provide projecting studs t which are fitted with wing nuts u thestuds being secured to the frame or case so that the vertical flat sliding plate When adjusted, can be held in the desired It is tobe, understoody that. the knives and'.

By providing theseadjustrnentl plates allowance is thereby made to enable the machine to be adapted-to any inequality in the width oithe cutting blades dueto excessive Wear or repeatedsharpening, Vandthe blades tlieinselies be slightly slotted opposite to the bolts. o rfstuds@ so as to enableV them toV be` moved backwards; or forwards, as may; be necessary, and it Willfbevunderstoodtliat the machine rnay bevaried in size to suit-the, di derent classes: of skins or pelisx which.. are'v to be icshcd thereby?
